It might make the most sense to just sell your primary residence and use it as 40% to 50% down payment on your future home. 

I have experience with this in Ohio, but usually much larger parcels of land to split.

Why not take out a smaller mortgage on the home and use some of that money to buy a second home?  

You will start with the larger pieces and fill in with accessories, wall art, rugs, and decor.Because I own cabins in a mountain environment, I try to avoid the new case goods.

It will save you a ton of money upfront and you'll gain the experience to upgrade to larger deals.  

We had one where they wanted us to pay for the majority of the costs to replace 1 mile of sewer back to a larger main.  

I take 2000 sq ft homes and add bedrooms. 

There is no point in looking at a home that can not reasonably obtain a permit.

Also, for people who wish to pursue larger real estate ventures, you don't personally need to be able to analyze a deal, and can possibly partner with someone who does or even hire an underwriter.

You are essentially doing a partial sale of your home.
